Audio crackles and pops, rear jack doesn't seem to work at all.
What crackles and pops so far: USB DAC Asus Xonar U5 (always, horrible), Monitor out through DisplayPort (NAVI 10 card) (rarely and it goes berserk after wake)
What doesn't work at all: Motherboard rear jack connector for some reason (yes I selected it)
What works well: Headphone front jack, HDMI audio to TV (NAVI 10 card)
Since the system is immutable I couldn't try ChatGPT's magic. I am also a Linux noob and this is a leisure gaming machine thats why I choose Bazzite, also Windows is annyoing lately.
I am also curious why linux doesn't have any GUI for sample rate and bitrate change?

I also suffers from this issue, audio crackles when the 3.5mm cable is connected through monitor, no problem when direct connect to 3.5mm audio jack at the motherboard, rolling back to stable-20250731 solve the crackling noise
Other people as well as I seen on forums, but this is an old issue, it probably got fixed then something broke it again. I dug up my FiiO KA11 and it seems to be working flawlessly, only problem is that it is running on 44Khz and there is no option to change that...
